Advanced Operation
7.5.5 External Terminal Functions: H
7 - 64
D
With this setting, the multi-function input selects the input method for the frequency reference and run
command.
D
The input method can be switched only when the Inverter is stopped.
D
The Digital Operator LOCAL/REMOTE Key is disabled when this function has been set in a multi-
function input.
Option Card/Inverter Selection (Setting: 2)
OFF
The Inverter frequency reference is enabled.
ON
The Option Card frequency reference is enabled.
D
With this setting, the multi-function input enables the frequency reference input from the Inverter itself
or the one from Option Card. The frequency reference input can be switched only when the Inverter is
stopped.
D
Be sure that b1-01 (the frequency reference source selector) has been set to 0 (Operator) or 1 (external
terminal). Only the frequency reference from the Option Card will be enabled if b1-01 is set to 3 (Option
PCB).
D
Setting 2 can’t be selected if the AI-14B is being used and constant F2-01 (AI-14 Input Selector) is set
to 0.
External Baseblock NO (Setting: 8)
OFF
Normal operation
ON
Baseblock
External Baseblock NC (Setting: 9)
OFF
Baseblock
ON
Normal operation
D
With either of these settings, the multi-function input controls baseblock operation.
D
Baseblock is an interruption of the Inverter output. The motor coasts while the baseblock command is
being input.
D
The output frequency is retained internally, so the same frequency will be output again when the base-
block command is cleared. The output frequency will change in a step pattern when the output resumes,
so take some safety precaution such as turning OFF the run command -- especially if the baseblock com-
mand was input when the motor was operating at high speed. (When the run command is turned OFF,
the internally retained output frequency is reset to zero.)
D
After a baseblock command is cleared, the voltage will be restored in the voltage recovery time set in
L2-04.
